ABSTRACT

A method for forming a wrapping material for hygiene articles involves: providing one of the inner edge portion and the outer edge portion of the edge zone of the first region with a first resealable adhesive, such that the other of the inner edge portion and the outer edge portion of the edge zone of the first region is adhesive-free; providing one of the inner edge portion and the outer edge portion of the edge zone of the second region with a first resealable adhesive, such that the other of the inner edge portion and the outer edge portion of the edge zone of the second region is adhesive-free; and providing at least one of the first central portion of the first region and the second central portion of the second region with a second adhesive; wherein the steps a-c are performed simultaneously.

TECHNICAL FIELD

The present disclosure relates to a method for forming a wrapping sheetfor hygiene articles, wherein the wrapping sheet provides a tightlysealed package both when packaging a new and disposing of a used hygienearticle.

BACKGROUND

Disposable hygiene articles, such as sanitary napkins and panty liners,are normally packaged individually in e.g. a single wrap or a quickwrap. A single wrap is formed from a sheet of material, such as aplastic film. In order to prevent the garment-affixing adhesive,provided on the garment-facing side of a hygiene article, from beingcaught by the single wrap material, the garment-affixing adhesive isusually protected by a release liner formed from a material having a lowadhesive force to the garment-affixing adhesive. Before arranging thehygiene article in the garment, the user has to remove the single wrapmaterial, and subsequently remove the release liner, thus exposing thegarment-affixing adhesive. Using a single wrap has the disadvantage ofintroducing an additional step during handling of a hygiene article. Inorder to overcome this disadvantage, a quick wrap is offered, being asingle wrap with a release paper permanently attached to it, forinstance by means of a construction adhesive, which means that both thesingle wrap and the release liner are removed in one single step.

Individual packages facilitate hygienic carrying of single articles forfuture use, e.g. in a handbag. The edges of the individual packages areoften sealed by means of ultrasonic welding or heat welding. Further,the packaging units are often used both as a means for packaging anunused article and for disposal of the used article.

It is desirable that used articles of this kind can be disposed ofdiscretely and hygienically. This may be particularly important when theuser lacks the possibility to dispose of the used article immediatelyafter the used article has been replaced, e.g. when there is no wastebin available in the toilet area. In this case, the user may need to putthe used article in e.g. her handbag or backpack, which requires thepackage to be adequately sealed in order to avoid staining and odour.

One solution addressing the disposal problem has been suggested in WO2013/162430, describing a wrapping sheet being formed from a sheethaving at least one folding axis dividing the sheet into a first regionand a second region. The inner surface of the first region comprises aninner edge portion and an outer edge portion, wherein one of theportions is provided with adhesive, and the other of the portions isadhesive-free. Further, one of the inner and outer edge portions of thesecond region is either provided with adhesive or is adhesive-free in acomplementary manner to the first region. Thus, when the sheet is foldedabout the folding axis, the edge portions carrying adhesive in the firstregion are brought in contact with the adhesive-free edge portions inthe second region, and the edge portions carrying adhesive in the secondregion are brought in contact with the adhesive-free edge portions inthe first region. The wrapping sheet disclosed in WO 2013/162430provides an improved sealing both when packaging a new hygiene article,and when the wrapping sheet is used for disposal of a soiled hygienearticle.

However, the manufacturing process of a wrapping sheet described in WO2013/162430 may be adversely affected by the presence of adhesive zones.For instance, when the wrapping sheet of WO 2013/162430 is a quick wrap,the adhesive arranged at the edge portions of the wrapping sheet mayhave a negative impact on the step of arranging the release liner of thequick wrap.

Hence, there is a need for a method for forming a wrapping sheet whichcan be used both for packaging a new hygiene article and for hygienickeeping and disposal of the used hygiene article, which is aestheticallyappealing and which facilitates manufacturing.

SUMMARY

The present disclosure provides a method for forming a wrapping sheetfor hygiene articles which substantially eliminates the drawbacks of themethods for forming packaging units discussed above.

The present disclosure provides a method for forming a wrapping sheetproviding a possibility of forming a tight package both for a new and aused article, thus keeping the new article sanitary and clean prior touse, and eliminating the risk of staining and odour when a used articleis packaged. The wrapping sheet manufactured according to the method ofthe present disclosure is easy to unfold and reseal, is aestheticallyappealing, and provides facilitated manufacturing.

As used herein, the term “inner surface” refers to the surface of thewrapping sheet facing the product positioned inside the packaging unit,and the term “outer surface” refers to the surface opposite to the innersurface, i.e. the surface facing the ambient.

By the term “edge zone” is meant the portion of the wrapping sheetadjacent to the edges of the packaging unit. The width of an edge zonemay be varied.

The term “inner edge portion” refers to the portion of the edge zonepositioned towards the centreline of the packaging unit.

The term “outer edge portion” refers to the portion of the edge zonepositioned towards the edge of the packaging unit.

The term “central portion” refers to the portion of the wrapping sheetexcluding the edge zone.

By the term “single ply” is meant a wrapping sheet comprising a singleply of a coherent material. The examples of a single ply wrapping sheetmay be a plastic film, such as a polyethylene film, a nonwoven material,a metallic foil or the like. A single ply material may be anon-homogenous material such as a plastic film material comprisingintegrated layers or a nonwoven material having varying fibrecomposition in different parts of the material. A single ply material asused herein does not comprise materials having separable layers.

By the term “laminate” is meant a wrapping sheet comprising at least twounited separable plies of material that can be the same or different. Inthe context of the present disclosure, the laminate may for example beconstituted of two separable plies of plastic film, a film and nonwoven,two plies of nonwoven or the like.

By the term “permanently attached” is meant two surfaces being in such acontact with each other that it is not possible to break the contactwithout affecting either or both surfaces.

“Releasably affixed” means two surfaces being bonded to each other suchthat the bond may be readily broken without affecting the surfaces.

By the term “resealable adhesive” is meant an adhesive that provides anon-permanent adhesive bond between two adherent surfaces, i.e. a bondthat may be broken by applying a pulling force to the adherent, andrecreated by applying a pressing force to the adherent.

A method according to the present disclosure is suitable for forming awrapping material for hygiene articles from a continuous web of wrappingsheets. Each wrapping sheet has an inner surface and an outer surface,wherein the inner surface comprises an edge zone comprising an inneredge portion and an outer edge portion. The wrapping sheet has at leastone first folding axis dividing the wrapping sheet into a first regionand a second region, wherein the first region comprises a first centralportion, and the second region comprises a second central portion.

The method according to the present disclosure comprising the steps of:

-   -   a. providing one of the inner edge portion and the outer edge        portion of the edge zone of the first region with a first        resealable adhesive, such that the other of the inner edge        portion and the outer edge portion of the edge zone of the first        region is adhesive-free;    -   b. providing one of the inner edge portion and the outer edge        portion of the edge zone of the second region with a first        resealable adhesive, such that the other of the inner edge        portion and the outer edge portion of the edge zone of the        second region is adhesive-free in a complementary manner to the        edge zone of the first region;    -   c. providing at least one of the first central portion of the        first region and the second central portion of the second region        with a second adhesive.

The steps a-c are performed simultaneously. In other words, the firstresealable adhesive and the second adhesive are applied simultaneouslyas a single manufacturing step. This is a great advantage since themanufacturing process is facilitated, and the risk of the subsequentsteps of the manufacturing sequence being affected by the presence ofthe first resealable adhesive at the edge zones is minimized.

The width of the adhesive-covered edge portions may be varied dependingon the adhesive strength desired. The wider the adhesive-covered edgezones, the stronger the sealing. The width of the adhesive-covered edgeportions may be same or different in the different regions.

Preferably, the length of the adhesive-covered edge portions in eachregion is equal to the length of each region. Also, the length of theadhesive-covered edge portions in each region may be shorter than thelength of each region.

The entire first and/or second central portion may be provided with thesecond adhesive. Preferably, only a portion of the first and/or thesecond central portions is provided with the second adhesive. Such anembodiment has the advantage of minimizing the consumption of the secondadhesive, and consequently the manufacturing costs. Further, if only aportion of the first and/or second central portion is provided with thesecond adhesive, the manufacturing is facilitated, since the risk of thesecond adhesive affecting the subsequent manufacturing steps isminimized.

The method according to the present disclosure may further comprise thesteps of:

-   -   d. providing a release liner having a wrap-facing surface and a        user-facing surface;    -   e. bringing the wrap-facing surface of the release liner in        contact with the inner surface of the wrapping sheet such that        at least a portion of the wrap-facing surface of the release        liner becomes permanently attached to the inner surface of the        wrapping sheet in at least the first and the second central        portions being provided with the second adhesive by means of the        second adhesive.

The release liner may be manufactured from any suitable material knownto the person skilled in the art, such as paper, non-woven or plasticfilm material. Further, in order to provide a release liner that iseasily detachable from the garment-affixing adhesive that may be presenton the garment-facing surface of the hygiene article, the release linermay be silicone-coated on the user-facing surface of the release liner.

The release liner may have substantially the same shape as the hygienearticle inside the packaging unit, or may have the shape being differentfrom the shape of the hygiene article. The size of the release liner mayvary. Preferably, the longitudinal extension of the release liner is60-100% of the longitudinal extension of the wrap. The transverseextension of the release liner may be 30-90% of the transverse extensionof the wrap.

The release liner may further comprise a print in the form of a text, agraphic, a symbol or a combination thereof. The print may be arranged onthe user-facing surface of the release liner, on the wrap-facing surfaceof the release liner, or on both the user-facing surface and thewrap-facing surface of the release liner.

It is sufficient that a portion of the release liner is attached to aportion of the inner surface of the wrap to thereby be in contacttherewith. Thus, only a portion of the release liner may be attached tothe central portion of the inner surface of the wrap being provided withthe second adhesive. Alternatively, the entire wrap-facing surface ofthe release liner may be attached to the inner surface of the wrappingsheet. Preferably, two or three portions of the release liner areattached to the inner surface of the wrap, wherein the portions of thewrap-facing surface of the release liner that are attached to the innersurface of the wrap are spaced apart along the longitudinal direction ofthe release liner. The release liner is permanently attached to the wrapby means of the second adhesive. The second adhesive may be of any typeknown to a person skilled in the art, such as a construction adhesive.

The method according to the present disclosure may further comprise thestep of:

-   -   f. releasably affixing a hygiene article to the user-facing        surface of the release liner.

The hygiene article may be releasably affixed to the release linereither by means of a third resealable adhesive or by any other suitablefastening means known to the person skilled in the art, e.g.hook-and-loop fastening means.

The hygiene article may be releasably affixed to the user-facing surfaceof the release liner after the release liner has been permanentlyattached to the inner surface of the wrapping sheet, i.e. step f occursafter step e. Alternatively, the hygiene article may be releasablyaffixed to the user-facing surface of the release liner before therelease liner has been permanently attached to the inner surface of thewrapping sheet, i.e. step f occurs before step e.

As mentioned above, the hygiene article may be releasably affixed to therelease liner by means of a third resealable adhesive. The methodaccording to the present disclosure may thus further comprise the stepof:

-   -   g. providing the user-facing surface of the release liner with a        third resealable adhesive;

wherein step g occurs before step f.

After the hygiene article has been arranged on the release liner beingpermanently attached to the inner surface of the wrapping sheet, thewrapping sheet may be folded in order to form a tight package around thehygiene article. The method according to the present disclosure mayfurther comprise the step of:

-   -   h. folding the wrapping sheet about the first folding axis such        that the edge portions carrying the first resealable adhesive in        the first region are brought in contact with the adhesive-free        edge portions in the second region, and the edge portions        carrying the first resealable adhesive in the second region are        brought in contact with the adhesive-free edge portions at the        first region.

The first resealable adhesive used with the wrapping sheet is one whichhas a very high self-adhesion but which can be readily separated orreleased from other materials, such as plastic materials or paper whichhas been treated with a release agent. As the adhesive-coated edgeportions of the wrapping sheet of the present disclosure are not incontact with each other when the wrapping sheet is folded, the wrappingsheet can be readily opened and resealed, providing a tight disposalpackage. At the same time, the tensile strength of the adhesively sealededges of the wrapping sheet using the adhesive pattern of the presentdisclosure is sufficient to provide a tight package for both a new and aused article, and low enough to provide a readily-opened package.

The geometrical shape of the wrapping sheet can vary depending on thetype of the hygiene article to be packaged. The wrapping sheet may becircular, triangular, square, rectangular, or any other shape suitablefor the hygiene article to be packaged. It is desirable, however, thatthe wrapping sheet has at least one symmetry axis.

As mentioned above, the wrapping sheet comprises at least one foldingaxis. The number of folding axes may vary depending on how the wrappingsheet is intended to be folded. It is preferred that the wrapping sheetcomprises from one to three folding axes.

The prevailing shape of the wrapping sheet of material for forming awrapping sheet is square or rectangular. Such a wrapping sheet accordingto the present disclosure has side edges, referred to herein aslongitudinal edges, a first and a second transverse edge and cornerportions, the edge zones of the first and second regions of the wrappingsheet of material being arranged along the longitudinal edges. The edgeportions covered with the first resealable adhesive and adhesive-freeportions are thus positioned along the longitudinal edges. Preferably,the resealable adhesive arranged at the outer edge portions ispositioned such that it extends all the way to the longitudinal edges ofthe sheet.

The first transverse edge zone is provided at the transverse edge of thefirst region. The positioning of the second transverse edge zone dependson the number of folding axes. When the wrapping sheet comprises onefolding axis, the second transverse edge zone is arranged at thetransverse edge of the second region. When the wrapping sheet comprisestwo folding axes, the second transverse edge zone is arranged at thetransverse edge of the third region, and so forth.

The wrapping sheet may have a first and a second folding axis dividingthe sheet into the first region, the second region and a third region.In such an embodiment, the method according to the present disclosuremay further comprise the steps of:

-   -   i. providing a portion of the edge zone of the third region with        the first resealable adhesive;    -   j. folding the wrapping sheet about the second folding axis such        that the inner surface of the third region is brought in contact        with the outer surface of the first region.

Preferably, step i is performed simultaneously with steps a-c, i.e. thefirst resealable adhesive is applied to the edge portions of all threeregions simultaneously with the second adhesive being applied to atleast one central portion of the first and the second regions. Also,step i may occur after steps a-c, but before step d. The first resalableadhesive may be arranged in any of the inner and the outer edge portionsof the third region.

Step j may be performed after step h, i.e. folding may be initiatedaround the first folding axis. If the first resalable adhesive isarranged in the edge portions of the third region being corresponding tothe adhesive-carrying edge portion of the second region, the foldingorder may be reversed, i.e. step j may be performed before step h. Thus,the folding may be initiated around the second folding axis, bringingthe portions carrying the first resealable adhesive in the third regionin contact with the adhesive-free edge portions in the second region,and bringing the edge portions carrying the first resealable adhesive inthe second region in contact with the adhesive-free edge portions at thethird region.

The method according to the present disclosure may further comprise thestep of:

-   -   k. providing at least one of the transverse edge zones of the        wrapping sheet with the first resealable adhesive.

wherein step k is preferably performed simultaneously with the stepsa-c.

Preferably, the first transverse edge zone of the first region of thewrapping sheet is provided with the first resealable adhesive, while thesecond transverse edge zone of the wrapping sheet is adhesive-free. Whenthe wrapping sheet comprises one folding axis, it is conceivable that aportion of the first transverse edge zone of the first region isprovided with the first resealable adhesive, while the remaining portionof the first transverse edge zone of the first region is adhesive-free,and a portion of the second transverse edge zone of the second region isprovided with the first adhesive, while a remaining portion of thesecond transverse edge zone of the second region is adhesive-free in acomplementary manner to the transverse edge zone of the first region.Thus, when the wrap is folded about the first folding axis, thetransverse edge portion carrying the first resealable adhesive in thefirst region is brought in contact with the adhesive-free transverseedge portion in the second region, and the transverse edge portioncarrying the first resealable adhesive in the second region is broughtin contact with the adhesive-free transverse edge portion in the firstregion. Also, both the first and the second transverse edge zones of thewrapping sheet may be provided with the first resealable adhesive whenthe wrapping sheet comprises at least two folding axes.

In order to facilitate opening, at least one of the corner portions maybe free from the first resealable adhesive such that a gripping tab isformed.

The first resealable adhesive and the third resealable adhesives may bepressure-sensitive adhesives, such as Lunatack® D656 BD 19 availablefrom H. B. Fuller, and the second adhesive may be a constructionadhesive.

The wrapping sheet and/or the release liner may be opaque and/orcomprise print.

The wrapping sheet for forming a wrapping sheet may be a single plysheet of any suitable material known to the person skilled in the art,such as polyethylene film or nonwoven. The wrapping sheet may also be alaminate comprising at least two distinct layers. Laminates suitable forpackaging of hygiene articles are assumed to be known to the personskilled in the art, and are not in any way limiting for the presentdisclosure.

The wrapping sheet of material forming a wrapping sheet according to thepresent disclosure may comprise an odour-inhibiting orodour-neutralising substance. Such a substance may be applied in anysuitable manner known to the person skilled in the art, e.g. as acoating, activatable microcapsules, impregnated patches or the like.Further, such a substance may be arranged on or in the user promptingdevice. Preferably, such a substance is integrated into the userprompting device in order to avoid the need for an additional material.

It is conceivable that the wrapping sheet for forming a wrapping sheetaccording to the present disclosure may be stretchable or expandable,which may be advantageous if the hygiene article is greatly deformedduring use, and may thus be difficult to wrap without deforming thepackaging unit.

The continuous web of wrapping sheets is then moved to the next step ofthe manufacturing sequence. According to FIG. 5, the next step in themanufacturing sequence is steps d-f, wherein step f is performed beforestep e. Thus, in step d, a release liner 115 is provided having awrap-facing surface 116 and a user-facing surface 117. A hygiene article118 is releasably affixed to the user-facing surface 117 of the releaseline 115, according to step f of the method of the present disclosure.The wrap-facing surface 116 of the release liner 115 is subsequentlybrought in contact with the inner surface 102 of the wrapping sheet 100according to step e, such that a portion of the wrap-facing surface 116of the release liner 115 becomes permanently attached to the innersurface 102 of the wrapping sheet 100 in the central portions beingprovided with the second adhesive 13 by means of the second adhesive 13.

Yet another embodiment of the method of the present disclosure is shownin FIGS. 6-8. FIG. 6 depicts steps a-c and i of the method of thepresent disclosure, the steps performed simultaneously and being:

-   -   a. providing the outer edge portion 206 of the edge zone of the        first region 210 with a first resealable adhesive 12, such that        the inner edge portion 205 of the edge zone of the first region        210 is adhesive-free;    -   b. providing the inner edge portion 208 of the edge zone of the        second region 211 with a first resealable adhesive 12, such that        the outer edge portion 207 of the edge zone of the second region        211 is adhesive-free in a complementary manner to the edge zone        of the first region 210;    -   i. providing the outer edge portion 206′ of the edge zone of the        third region 212 corresponding to the adhesive-carrying outer        edge portion 206 of the edge zone of the first region 210 with a        first resealable adhesive 12, such that the inner edge portion        205′ of the edge zone of the third region 210 is adhesive-free;        and    -   c. providing the central portions of the first region 210, the        second region 211 and the third region 212 with a second        adhesive 13.

The continuous web of wrapping sheets 200 is then moved to the next stepof the manufacturing sequence. According to FIG. 7, the next step of themanufacturing sequence according to the embodiment shown in FIGS. 6-8 isstep k, i.e. providing the first transverse edge zone 204′ of thewrapping sheet 200 with the first resealable adhesive 12. As mentionedabove, step k. may be performed simultaneously with steps a-c.

According to FIG. 8, the subsequent step in the manufacturing sequenceis steps d-f, wherein step f is performed before step e. Thus, in stepd, a release liner 215 is provided having a wrap-facing surface 216 anda user-facing surface 217. A hygiene article 218 is releasably affixedto the user-facing surface 217 of the release line 215, according tostep f of the method of the present disclosure. The wrap-facing surface216 of the release liner 215 is subsequently brought in contact with theinner surface 202 of the wrapping sheet 200 according to step e of themethod of the present disclosure, such that a portion of the wrap-facingsurface 216 of the release liner 215 becomes permanently attached to theinner surface 202 of the wrapping sheet 200 in the central portionsbeing provided with the second adhesive 13 by means of the secondadhesive 13.
